... I use them in my spec ops reflex and my friend uses one in his scope. To give you an idea of how long the battery lasts, it's a 3 volt. An AA is 1.5 volts. These last me about 5 battles before they die. They look a little odd, round and flat like a penny (in case they still haven't put the picture up yet). You may think your battery is defective but it fits right once you move it a bit. Where i get them they're $5, while the total here is only 1.09 counting shipping(not the base charge).
As i said in the title, they're cheap, they work and last long. I suggest you buy in bulk so you don't have to pay repeated base shipping charges.
I haven't used this specific one, they say it's for the spec ops reflex sight, but about a month ago they sent me an e-mail because i forgot the type, they said it was CR2025, and this is a CR2032, i don't really know the difference.

These batteries are great. They only cost $1 each compared to the $5 you can spend at stores buying button batteries, so you're better off buying in bulk. In the scope I have (the UTG TACTEDGE 4X40), they last pretty long, so you don't have to worry about your batteries dying during a game. Plus, they're so small you can just keep a few extras with you on the field in case your battery does die. For only $1, these batteries are a great value, so if you buy a scope or red dot, you should stock up on these too.

A pair of these came with my UTG red/green dot scope/sight. These things last forever. I have left the sights on overnight and/or all day at least three times and used it for more than 5 hours which I would calculate to be equal to at least 36 hours of use. The light has just started to dim.

These are great for sights requiring power including ones with multiple brightness settings.
The price looks good, just gotta put a few in my next purchase here at Shorty.
